Infinite tape loops are quite the rabbit hole to venture down. Hainbach was the one that started my journey.
This design wouldn’t be able to record more than a couple of seconds IMO because the reel cage is blocking where the tape could be fed back in like 8 tracks do. To be honest I KNOW how 8 tracks work but it still feels like a bit of black magic to me. The design just feels like it shouldn’t work and should get jammed constantly.
Even though the device says “Tape” on it the miniscule thickness of the cartridge makes me think some thing like a high density floppy disk is more likely.
Man, that kind of switch really rubs me the wrong way.
